MM145453V/NOPB Datasheet PDF - TI

●DESCRIPTION

●The MM145453 is a monolithic integrated circuit utilizing CMOS metal gate, low threshold

●enhancement mode devices. The chip can drive up to 33 LCD segments and can be paralleled to increase this number. The chip is capable of driving a 4½ digit 7-segment display with minimal interface between the display and the data source.

●The MM145453 stores display data in latches after it is clocked in, and holds the data until new display data is received.

●The MM145453 is available in a molded 44 pin surface mount PLCC package. The MM145453 is pin out and functionally compatible with the MC145453.
